I am not a wine person. Half a glass of any kind of wine gives me a terrible headache within a half-hour of drinking it. But I am very much into Red Obsession. This documentary starts out a bit slow and pompous, with some charming but rather inarticulate Bordeaux vintners trying to explain their passion for their craft, but after the first ten minutes or so it gets into the actual nuts-and-bolts marketing and distribution of Bordeaux wine and really hits its stride. While the recession’s taken out the traditional customers of the wineries (the U.S.), it’s brought to lightning-fast prominence a huge new market: China.
